For TByrne, go to thread on PT.net General Activity Forums:The Truck Stop. It's in there today.
As far Dynatechs, I have em on a 5.3(see sig.). No leaks, fit right( minor revisions followed on my style truck to make a good thing better). Sound louder on 6L due to 2 headpipes leading to muff. That may've changed on the new stuff. I talked to Corsa & told them about Dynatechs. I run their hi flo cat system. Corsa said go w/ Touring instead of Sport, Sport would be too loud. I'm happy w/sound @ any speed/ throttle input or under load. I wasn't gonna to get a Sport to check. As Allgonoshow said, perfect sound is subjective. My .02.

***, that's a lot of money... People seem to love em though, so I guess they're worth it... Im cheap, so I think I'm gonna get yank tt3000/pacesetters at the same time and pay about the same as getting just the dynatechs,LOL

The dynatechs came with cats so if you get pacesetters you gotta do some custom work to fit the exhaust to the headers, unless you can do it yourself there is an expense to that.
I owe a garage with a pipe bender and welding gear and i'd still rather have direct fit on my new truck. to each ...his own. you will be happy with the pacesteers as well.
